Abstract (en)

Method for estimating a pure tone hearing threshold or a pure tone audiogram of a person with a non-calibrated audio-system, comprising the steps of performing a supra-threshold test at least over a portion of the audible frequency spectrum, wherein the audible frequency spectrum ranges particularly from 16 Hz to 20.000 Hz, wherein the supra-threshold test is performed on an unreferenced audio-system at a first relative sound level relative to a predefined output level of the unreferenced audio-system, determining the result of the supra-threshold test for at least a portion of the audible frequency spectrum, wherein the results of the supra-threshold test are provided particularly relative to the predefined output level of the unreferenced audio-system, determining from the progression of the determined result of the supra-threshold test at least one absolute pure tone threshold, wherein the at least one absolute pure tone threshold is provided in absolute physical units, particularly in decibels hearing level or decibels sound pressure level.
